“…At present, with the increasing demands of higher power and energy density for lithium‐ion batteries (LIBs), developing advanced cathode material as a promising candidate applied in next‐generation LIBs is a great challenge. Compared with the most traditionally utilized Li intercalation materials such as LiCoO 2, [1–3] transition metal fluorides especially iron fluorides with merits of abundant source, relatively high theoretical capacity and high voltage are becoming attractively alternative cathode material [4–7] . The electrochemical reaction mechanism of FeF 3 ⋅ 0.33H 2 O with Li + is listed as follows:

true {FeF}_{3} \cdot 0 {. 33 normalH}_{2} normalO \leftrightarrow_{intercalation}^{{+ Li}^{+} {+ e}^{-}} {LiFeF}_{3} \cdot 0 {. 33 normalH}_{2} normalO \leftrightarrow_{conversion}^{{+ 2 Li}^{+} {+ 2 e}^{-}} 3 LiF + Fe \cdot 0 {. 33 normalH}_{2} normalO

FeF3 ⋅ 0.33H2O is considered as a potential candidate cathode material owing to the special structure with one‐dimension (1D) tunnel. However, its practical application is hindered by the poor electric conductivity. In this work, FeF3 ⋅ 0.33H2O embedded into N, S co‐doped porous carbon (NSPC) derived from antibiotic bacterial residues was synthesized by a facile wet‐impregnation method. Close contact of FeF3 ⋅ 0.33H2O nanoparticles with NSPC can provide the rapid electron conduction channel and keep the structural stability, which endows that FeF3 ⋅ 0.33H2O@NSPC electrode achieves excellent cycling performance with a reversible capacity of 164.5 mAh g−1 at 40 mA g−1 after 100 cycles between 2.0 and 4.5 V and good rate performance. This study offers a new method for high‐value utilization of antibiotic bacteria residues (ABRs) for application in energy storage.

“…The development of plug in hybrid electric vehicles (PHEVs) and electric vehicles (EVs) puts higher demands on energy density and cruising range [4][5][6]. Compared to traditional cathode materials, such as LiCoO 2 [7,8], spinel LiMn 2 O 4 [9,10], polyanionic LiFePO 4 [11,12], and layered cathode materials LiMO 2 [13][14][15][16] [17,18]. Unfortunately, these cathode materials put up with poor kinetics [19] and severe voltage attenuation [20][21][22] during prolong cycling, which directly affects their electrochemical performance, particularly the energy that the battery can output [23][24][25].…”

Li-rich layered oxide cathode materials have become one of the most promising cathode materials for high specific energy lithium-ion batteries owning to its high theoretical specific capacity, low cost, high operating voltage and environmental friendliness. Yet they suffer from severe capacity and voltage attenuation during prolong cycling, which blocks their commercial application. To clarify these causes, we synthesize Li1.5Mn0.55Ni0.4Co0.05O2.5 (Li1.2Mn0.44Ni0.32Co0.04O2) with high-nickel-content cathode material by a solid-sate complexation method, and it manifests a lot slower capacity and voltage attenuation during prolong cycling compared to Li1.5Mn0.66Ni0.17Co0.17O2.5 (Li1.2Mn0.54Ni0.13Co0.13O2) and Li1.5Mn0.65Ni0.25Co0.1O2.5 (Li1.2Mn0.52Ni0.2Co0.08O2) cathode materials. The capacity retention at 1 C after 100 cycles reaches to 87.5% and the voltage attenuation after 100 cycles is only 0.460 V. Combining X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscopy (TEM), it indicates that increasing the nickel content not only stabilizes the structure but also alleviates the attenuation of capacity and voltage. Therefore, it provides a new idea for designing of Li-rich layered oxide cathode materials that suppress voltage and capacity attenuation.

Metal‐Organic‐Framework‐Based Cathodes for Enhancing the Electrochemical Performances of Batteries: A Review

2019

View full text Add to dashboard Cite

Owing to their huge specific surface area, high porosity, abundant metal active sites, adjustable structure, and tunable pore diameters, metal-organic frameworks (MOFs) have attracted much attention from the battery scientists and technologists. MOFs have proven to be versatile precursors of cathode materials for batteries, and MOF-based cathodes have already exhibited excellent electrochemical performances. Herein, we review some recent advances in developing MOF-derived cathodes for lithium-/sodium-ion batteries, lithium-sulfur batteries, lithium-air batteries, and lithium-selenium batteries. We also describe the synthetic mechanism, characterization of MOF-derived cathodes, and the origin of the enhanced electrochemical performances. Finally, we point out some challenges and opportunities for the future development of MOF-based cathodes.
